Vesicular stomatitis virus, or VSV, has long been a model system for studying and understanding the life cycle of negative-strand RNA viruses, which include viruses that cause influenza, measles and rabies.
More importantly, research has shown that VSV has the potential to be genetically mod... Read More
This year I started a new virology course at Columbia University. The course emphasizes the common reactions that must be completed by all viruses for successful reproduction within a host cell and survival and spread within a host population. The molecular basis of alternative reproductive cycl... Read More

A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones. In the process, the insects rapidly transmit the disease, according to Penn State entomologists.
"The virus improves... Read More
Scientists have discovered a new and easier way to transform stem cells from human fat into induced pluripotent stem cells using virus-free techniques.
Experts at the Stanford University
School of Medicine have developed a novel method using minicircles, rings of DNA, to induce pluripotency ... Read More
In the past year, the media has hyped the swine flu as if it were the Black Death. People have been reminded to wash their hands to the point of excess.
